Abstract

PURPOSE: To obtain a chrominance signal without color fringing by performing orthogonal modulation of two color difference signals as to red and green, and blue and green by obtaining a red signal and blue signal from different lines while obtaining a green signal from every line.
CONSTITUTION: This generator, having pickup unit 1 obtaining every-line green signal G on its output side and pickup unit 2 obtaining red signal R and blue signal in line sequence on the output side, consists of synchronous board 3 supplying sampling signals to those units 1 and 2, sample holding circuits 4 and 7 for waveform shaping, process circuits 5 and 8 for (γ) correction, black-level setting, etc., matrix circuit 6 for obtaining green signal G and luminance signal Y at the output side of circuit 5, delay circuits 9 and 11, switches 12, 14, 15, and 16, subtraction circuits 13 and 16, amplifiers 18∼21, addition circuits 22, 24 and 26, balancing modulators 23 and 25, etc. In this constitution, line (n) is black and "0" in signal level, and line (n+1) is white and "1" in signal level while color difference signals are both "0", thereby improving the color fringing of a reproduced picture.
